Haha thanks for the reply, at least... I just went ahead and did it, and aside from not checking the photo carefully enough to notice that his switch was orientated 180 degrees from my own, it went off without a hitch (my first pass resulted in the LED turning off when the pedal was engaged and on when it was bypassed... kind of neat, but also not worth leaving like that).
Super easy, and super useful.
